Devulcanization of ground tire rubber by stress-induced reaction and its structure and mechanical properties of the revulcanized material
Pages: 44-48
Year: Issue:  3
Journal: Journal of Nanjing University of Technology(Natural Science Edition)

Abstract: 在轮胎胶粉(GTR)与三元乙丙橡胶(EPDM)的共混物熔融挤出过程中添加二硫化四甲基秋兰母(TMTD)和过氧化二异丙苯(DCP)作为脱硫反应促进剂,考察双螺杆挤出机的螺杆转速和挤出温度对再生胶(DGTR-EPDM)的凝胶含量、溶胶分子链结构及再硫化材料力学性能的影响.结果表明:加入TMTD有助于反应体系中自由基的链转移反应,有助于对脱硫产物中较活泼双键的保护作用.当同时加入TMTD和DCP作为脱硫...
